Gallium Arsenide (바카라 배팅)

Gallium Arsenide (바카라 배팅)

Use 바카라 배팅 for transmissive and reflective optics in applications where mechanical hardness, mechanical strength, and abrasion resistance are important.

Coherent produces 바카라 배팅 with the characteristics required for optical applications by applying laser vacuum calorimetry and other techniques to screen out material with voids, inclusions, or other defects that cause inferior optical performance.

Gallium Arsenide (바카라 배팅) Characteristics

Coherent supplies 바카라 배팅 substrates of up to 100 mm diameter, and carefully monitors 10.6 µm absorptivity to ensure that thermal runaway and fracture do not occur.
